Abstract: PURPOSE: A cell selection circuit is provided to reduce a lay-out area related to a word line driver by decreasing the number of gates for constituting the word line driver in a memory device. CONSTITUTION: The circuit includes an address decoding control unit(210), a logic gate unit(220) and a word line driving unit(230). The address decoding control unit activates a control signal(MRBLK) for decoding an address signal when selection signals(MBLK,RBLK) for respectively selecting a main cell and a repair cell are mutually an opposite level. The logic gate unit logically combines external address signals(X0TN-X2TN) when the output of the address decoding unit is low. The word line driving unit inputs an output of the logic gate unit, outputs word line driving signals(MWL,RWL) and activates one of the word line driving signal in response to the selection signals.

Abstract: PURPOSE: A method for controlling a vapor generator of a nuclear power plant using a neural-network is provided to simplify a complex vapor generator by using a neural-network as a universal function approximator. CONSTITUTION: A vapor generator which is a non-linear system is modeled in using a partial linear learning neural-network or a feedback neural-network. In a control step, a feedforward controller and a feedback PI controller are used by using the neural-network. An output of the controller is an amount of water supplied inputting into a plant. The output of the controller is calculated by adding an output of the neural-network feedforward controller and an output of the feedback PI controller. When an amount of vapor generation of the vapor generator high outputs, the feedback PI controller is formed by separating the feedback controller and the feedforward controller or by coupling the feedback controller and the feedforward controller. Accordingly, performance of controller is improved in a low output.
